TNFRSF5 (Tumor Necrosis Factor Receptor Superfamily, Member 5, CD40, CDW40, Bp50, P50, B-cell surface antigen CD40, CD40L receptor)

Antibodies / Antibodies-Apoptosis

-20°C

Supplied as a liquid in PBS, pH 7.4, 0.02% sodium azide, 50% glycerol.

Recombinant protein corresponding to Cys26-Arg193 of mouse TNFRSF5, fused to two N-terminal Tags, His-Tag and T7-tag, expressed in E. coli.

CD40 is a costimulatory protein found on antigen presenting cells and is required for their activation. The binding of CD154 (CD40L) on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects. The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor has been found to be essential in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. AT-hook transcription factor AKNA is reported to coordinately regulate the expression of this receptor and its ligand, which may be important for homotypic cell interactions. Adaptor protein TNFR2 interacts with this receptor and serves as a mediator of the signal transduction.
